  Moreover, it is preferable to set the thickness of the connection tool 6 to 2 mm-5 mm in the part in which the spot facing recessed part 63 is not formed. If this thickness is too thin, it may break. Moreover, when too thick, it is necessary to deepen the groove depth of the connection tool attachment grooves 43 and 53 of the baseboards 4 and 5, and the baseboards 4 and 5 may be broken.

  The width of each fitting portion 61, 61 of the connection tool 6 is preferably set to 15 mm to 50 mm. When this width is too narrow, there is a case where the horizontal baseboard 4 and the vertical baseboard 5 cannot be sufficiently fixed. On the other hand, if it is too thick, it may be difficult to attach to the baseboards 4 and 5.

  The outer length B of each fitting portion 61, 61 of the connection tool 6 is preferably set to 50 mm to 100 mm. That is, when this length is too short, there is a case where the horizontal baseboard 4 and the vertical baseboard 5 cannot be sufficiently fixed. On the other hand, if it is too long, fitting work to the baseboards 4 and 5 may become difficult.

  The depth of the spot facing recess 63 of the connection tool 6 is preferably set to 1 mm to 3 mm. When this depth is too shallow, when the tapping screw 65 is screwed into the counterbore recess 63 as will be described later, the screw head protrudes from the surface of the connection tool 6, and the connection tool 6 is connected to the baseboard. There is a possibility that it cannot be attached to 4,5. On the contrary, when the recessed part 63 is too deep, there exists a possibility of breaking.

  Needless to say, in the present embodiment, the thickness, width, length, recess depth, and the like of the connection tool 6 may be appropriately changed according to the size of the baseboards 4 and 5 used.

 In the present embodiment, when the baseboards 4 and 5 are attached to the corners between the indoor wall surface 1 and the staircase body using the connector 6, the baseboards 4 and 5 are connected to the staircase as shown below.
